Should probably build the file when debugfs is enabled and provide
no-op stub in the header. See nouveau for an example.


It seem that the drm core already done this for us, are we really need those #ifdef guard anymore?

I remove all of the  #ifdef CONFIG_DEBUG_FS in my program and disable the debugfs option in menuconfig

my driver compile without any error.
